SN2 reactions are single-step reactions. This means that the bond breaking and bond forming steps happen at the same time. This makes SN2 reactions very fast reactions.

The SN2 reaction mechanism is as follows:

• The nucleophile approaches the substrate from the backside.
• The nucleophile donates an electron pair to the substrate, forming a new bond.
• The leaving group leaves, forming a new bond with the nucleophile.

The entire reaction happens in one step, with no intermediates being formed. This is why SN2 reactions are so fast.

The SN2 reaction is favored by bulky nucleophiles and substrates with good leaving groups. Bulky nucleophiles are less likely to collide with the substrate in the wrong way, which can lead to the formation of an unfavorable intermediate. Good leaving groups are easily displaced by the nucleophile.

This option is incorrect.

SN2 (Substitution Nucleophilic Bimolecular) reactions are a type of reaction in organic chemistry where a nucleophile replaces a leaving group in a single step. The reaction involves simultaneous bond formation and bond breaking, resulting in the substitution of one group by another.

In an SN2 reaction, the nucleophile attacks the electrophilic carbon atom while the leaving group departs, leading to inversion of stereochemistry at the reaction center. The reaction occurs in a single step without any intermediate formation or rearrangement of the substrate molecule.

This option is incorrect.
